W-system filter

The W-system is integrated in the exhaust piping of the vehicle, mostly instead of the original muffler. The exchangeable filter system consists out of exhaust inlet unit, which is integrated on the vehicle and the exchangeable filter cartridges. The cartridges are connected to the exhaust inlet by fast-release clamps. The filter medium is (SiC) a high-tech ceramic. The filter is able to load the between 8 and 10 working hours. Then the maximum allowed backpressure is reached and the filter needs to be regenerated. Depending on the filter size, the regeneration is completely over in 1 to 1.5 hours. For this purpose the loaded cartridge is removed from the vehicle and put on an external electrical heating. The entire process is supervised by the HUSS ZA1 control device. The vehicle is equipped with a fresh, unloaded cartridge and can go on immediately.
